EDWIN 12.. LYON, or QUEEN, TERRITORY or NEW MEXICO.

' INSECT-DESTROYER.

To all whom it may concern:

Be it known that I, EDWIN R. LYN,.a citizen of the United States,residing at Queen, in the county of Eddy and Territory,

of New Mexico, have invented new and use- ,ful Improvements inInsect-Destroyers, of

which. the following is a specification;

' improve and simplify the construction and This invention relates toinsect destroyers andmore particularly to spraying devices of thevehicle type whereby a plurality of rows of plants can be sprayed as thevehicle is driven 'through the field The invention has for one of itsobjects to the plants, and whereby two or more rows can be sprayed atthe same time, the liquid being drawn from auxiliary tanks that areconnected with a common tank in which is contained acontinuously-operated agitator.

With these objects in view and others, as

. will appear as the description proceeds, the

hereinafter and set forth with particularly. in the claim appendedhereto.

invention comprises the various novel features 6f construction andarrangement of parts which, will be more fully described In theaccompanying. drawings, which illustrate-one.embodiment of theinvention, Figure 1 is a plan view of the machine. Fig. 2 is alongitudinal section thereof Fig. 3 is a transverse section. Figs. 4.and 5 are detail viewsof the pitman connections between thelpumpplungers and the crank I shaft.

Similar reference characters are employed I to designate correspondingparts through-.

out the views. Referring to the drawings, A designates the frame of thevehicle which may be of any approved construction and mounted on pumps,and on the ends of the axle are tracinstance, is conslsting 0 an axle 1that has its central portion arched to accommodate the auxiliary tanksand tion wheels 2; The vehicle, in the present rqvided with. a draftdevice f a' tongue 3 and whiiiletree 4. Arranged on the axle is a seat 5for the driver, the seat being conveniently arranged Specification ofLettersPatent. ,PatentedMar, 14, 1911 Application filed April 17, 1909.Serial No. 490,464. I

so that the valves for controlling the flow of the spraying liquid 'can'be manipulated.

Arranged at the front of .the vehicle frame is a transversely-extendingreservoir or main tank 6 that is held in place by straps 7 and in thetop of this tank is a fillingopening 8 which is normally closed by a cap9. Arranged within the tank is a central shaft 10 that carries aplurality'of agitating arms [1 whereby the liquid will be continuouslyagitated" during the move- 1ment of the vehicle, tliere beingpowertransmitting devices between the wheels 2 and shaft 10, whichdevices are in the form of sprocket chains 13 that pass around sprocketwheels 14 and 15 on the hubs of wheelsfl and ends'of the shafts 10,respectively. .In the present instance, the spraying machine is igned tospray two rows of plants at a time and for this purpose two sets ofpumps are employed which receive liquid from auxiliary tanks 16 arrangedin brackets 17 under the middle portion of the axle and extendinglongitudinally of the Vehicle.

Between the main tank- 7 and each auxil "iary tank is a supply pipe 18insuch a manner that liquid will flow from the former .'to the latter bygravity, and in each supply pipe is a-valve 19 whereby liquid can besupplied to either set of pumps. vUnder each auxiliary tank 16is acylinders 20 supported on the brackets 17 and in each pump is a piston21 that has a rod 22 extending out of the forward end of the tankthrough a packing box 23, and theseflplunger rods are connected with acrank shaft 24 that is supported in brackets 25 at the front end of themachine. The crank shaft is provided at its ends with air of parallelpump sprocket wheels 26 around -.which pass sprocket chains 27 that aredriven by sprocket wheels 28 on the hubs of the traction wheels 2,.Between each auxiliary tank 16 and adjacent pair of pumps is a branchsupply pipe 29 havin check valves 30 which permit the liquid to ow fromthe auxiliary tank to 'the respective pumps and this [fipe is providedwith a hand-controlled valve 31 whereby either auxiliary tank andadjacent pumps can'be closed, as for instance, when only one row ofplants is to be sprayed.- Attached to the rear ends of the pumpcylinders aredischarge pipes 32 that have check valves 33 and thesepipes areconnected together by a union 34, and attached transverselythrough the row and the other arallel there:

the invention appertains, and while I have- With so that the plants wille effectively sprayed by the insecticide liquid. ''Thepitman connectionbetween each piston rod and crank consists of two sections a and b, thesection a being in the form of a rod pivotally connected at its rear end37' with the,

plunger rod and having its forward end formed into a sphericalenlargement or ball 37 which is disposed in a socket or opening 38 inthe section b, there being a slot 'extending r'earwardly from the socketto present parallel -members 39 between which the rod a extends. The rodsection is-held in place with respectvto the section b by a bolt 40 thatextends through the members 39 and also through a slot 41 in the rodsection a. By this construction, the connecting bolt 40 is subjectedto-no strain, since the enlargement 37 bears against, the walls of thesocket 38 at a, when the pump piston ismoved forwardlyand bears againstthe wall of the socket at (2 during the rear strokes ofthe piston. Thesection b of the pitmanisprovided with a bearing 42 for receiving thecrank pin 43 of the shaft 24. F

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readiig apparent to those skilled in the artto whi described' the principle of operation of the invention, togetherwith the apparatus which I now consider to be the best embodimentthereof, I desire to have it understood that the apparatus shown ismerely illustrative, and that such changes may be made scope of theextending horizontally and disposed longitudinally of the machine,acommon means for rigidly supporting the cylinders and auxiliary tankson the said frame, and a s raying device connected with the discharge ofeach pump.

In testimony whereof I afiix my signature in presence of twowitnesses.
